* omp-low.c (extract_omp_for_data): For collapsed loops, if at least one of the loops is known at compile time to iterate zero times, set count to 0. (expand_omp_regimplify_p): New function. (expand_omp_for_generic): For collapsed loops, if at least one of the loops isn't known to iterate at least once, add runtime check with setting count to 0. (expand_omp_for_static_nochunk, expand_omp_for_static_chunk): For unsigned types if it isn't known at compile time that the loop will iterate at least once, add runtime check to bypass the whole loop if initial condition isn't true. * testsuite/libgomp.c/loop-13.c: New test. * testsuite/libgomp.c/loop-14.c: New test. * testsuite/libgomp.c/loop-15.c: New test. * testsuite/libgomp.c++/loop-13.C: New test. * testsuite/libgomp.c++/loop-14.C: New test. * testsuite/libgomp.c++/loop-15.C: New test.
